It is wired to be compliant with legal requirements. The CO detector is a life-saving device, the manufacturer can not with good conscience allow that to be accidentally turned off. Same with the breakaway switch -- a safety device.
The critical circuits are simply connected ahead of the OEM mislabeled "battery cutoff".
If you want, get behind the switch (remove or find the access panel) and move the safety systems wiring to the other side of the switch. Your RV will no longer be compliant, but it will be your problem, not Jayco's.
